Description

Technical Field

[0001] This utility model relates to the field of ion exchange tree filtration technology, specifically a polymer electro-ion exchange resin regeneration device. Background Technology

[0002] Ion exchange resin is a solid granular material with a strong ion exchange capacity. It can change the chemical properties of a solution by adsorbing or releasing ions. Ion exchange resin is widely used in water softening, heavy metal removal, pH adjustment and other fields, and is one of the important ion exchange materials.

[0003] After a period of use, ion exchange resins require a specialized regeneration device to reactivate the internal ions. Existing regeneration devices typically require the ion exchange resin to be statically placed inside the regeneration vessel, waiting for the regenerant (equivalent to the cleaning solution in this application) to react naturally with the resin. This method of immersing the ion exchange resin in the regenerant cannot completely remove surface contaminants, or rather, because the resin remains static, the contaminants adhering to the resin surface cannot be completely removed. Therefore, we propose a polymer electro-ion exchange resin regeneration device. Utility Model Content

[0006] Preferably, the support frame includes a mounting platform and a base arranged parallel to the mounting platform below it. The base and the mounting platform are connected at their four corners by support rods. The filter box is installed inside the mounting platform, and the first pump body and the second pump body are installed on the base.

[0007] Preferably, a support ring is provided above the adsorption layer. The support ring is detachably installed on the first annular seat, which is connected to the inner wall of the filter box. A support mesh is provided inside the support ring, and the filter layer is located on the support mesh.

[0008] Preferably, a control cabinet is provided on the top of the base, and a controller is provided inside the control cabinet. The controller is electrically connected to the first pump body and the second pump body respectively. The controller is also electrically connected to two liquid level detectors, one of which is located on the top of the filter box and the other is located below the support net.

[0009] Preferably, the top of the sealing cap is provided with a feeding port and a suction pipe. The feeding port is sealed by a detachable cap. The bottom of the suction pipe extends into the top of the tank. The pipe located at the inlet of the first pump body is detachably connected to the top of the suction pipe, while the pipe connected to the outlet of the second pump body is connected to the bottom of the tank.

[0010] Preferably, a blocking net is provided below the suction pipe, and an annular ring is provided at the edge of the blocking net.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 4 This utility model provides a technical solution: a polymer ion exchange resin regeneration device, including a tank 1. Multiple legs 15 are provided at the bottom of the tank 1, supporting the tank on the ground. Ion exchange resin is placed inside the tank 1, with the height of the ion exchange resin lower than the top of the tank 1. A detachable sealing cover 3 is provided at the top of the tank 1, specifically, the edge of the sealing cover 3 is fastened to the top of the tank 1 with bolts. A water inlet pipe 2 is provided on one side of the sealing cover 3, and a water outlet 16 is provided at the bottom of the tank 1. In actual use, external water to be filtered enters the tank 1 through the water inlet pipe 2. A water distributor connected to the water inlet pipe 2 is provided inside the sealing cover 3. The water distributor can disperse and drop the water flowing in from the water inlet pipe 2. Figure 3 As shown by the hollow arrow, the scattered water falls evenly on top of the ion exchange resin. The water flows from the top of the ion exchange resin to its bottom. After being purified by the ion exchange resin, the water is discharged from the outlet 16.

[0022] Furthermore, this application also includes a support frame, which includes a mounting platform 10 and a base 12 arranged parallel to the mounting platform 10 below it. The base 12 and the mounting platform 10 are connected at their four corners by support rods 11, making the base 12 and the mounting platform 10 an integral structure. A filter box 7 is provided on the top of the support frame, specifically, the filter box 7 is installed inside the mounting platform 10.

[0023] The filter box 7 contains a filter layer and an adsorption layer arranged from top to bottom. To support the filter layer, a support ring 8 is provided above the adsorption layer. The support ring 8 is detachably installed on the first annular seat 21. In actual use, the support ring 8 is fastened to the first annular seat 21 with bolts. The first annular seat 21 is connected to the inner wall of the filter box 7. A support mesh 19 is provided inside the support ring 8. The filter layer is located on the support mesh 19. The filter layer is filter cotton placed above the support mesh 19. The filter cotton is one or more layers stacked. The adsorption layer is activated carbon 24 placed below the support mesh 19. The activated carbon 24 can be placed directly inside the filter box 7.

[0024] Furthermore, a first pump body 13 and a second pump body 14 are provided in the lower part of the support frame, specifically the first pump body 13 and the second pump body 14 are mounted on the base 12. The outlet of the first pump body 13 is connected to the liquid outlet pipe 6 through a pipe. The liquid outlet pipe 6 is located above the filter box 7. The inlet of the first pump body 13 is connected to the tank 1 through a pipe. It should be emphasized that the pipe located on the inlet of the first pump body 13 is detachably connected to the top of the suction pipe 5, that is, the two are connected through a flange or quick-release pipe joint. The suction pipe 5 is installed on the top of the sealing cover 3 and the bottom of the suction pipe 5 extends into the top of the tank 1.

[0025] The inlet of the second pump body 14 is connected to the bottom of the filter box 7 via a pipe, and the outlet of the second pump body 14 is connected to the tank 1 via a pipe. It should be emphasized that the pipe connecting the outlet of the second pump body 14 is connected to the bottom of the tank 1, that is, the two are connected via a flange or a quick-release pipe joint.

[0026] Furthermore, such as Figure 3 As shown, a blocking net 23 is provided below the suction pipe 5. The blocking net 23 prevents the ion exchange resin from passing through. The edge of the blocking net 23 is provided with an annular ring. The annular ring is detachably installed on the second annular seat 22. That is, the two are fixed together by bolts. The second annular seat 22 is connected to the inner wall of the tank 1. The ion exchange resin is located below the blocking net 23, and the blocking net 23 is provided with a certain distance from the suction pipe 5 and the top of the ion exchange resin.

[0027] Based on the above embodiments, the specific operation method of the polymer electro-ion exchange resin regeneration device proposed in this application is as follows: when the tank 1 has been used for a preset time, the ion exchange resin inside it needs to be cleaned.

[0028] Before cleaning the ion exchange resin, close the valves on the inlet pipe 2 and the outlet 16, and then drain the water from the tank 1 through the drain valve at the bottom. Figure 1 As shown, a feeding port 4 is provided on the top of the sealing cap 3. The feeding port 4 is sealed by a detachable cap and the two are connected by threads. The cleaning liquid is added into the tank 1 through the feeding port 4. The cleaning liquid reaches the sealing cap 3. At this time, the bottom of the suction pipe 5 is located in the cleaning liquid.

[0029] It should be noted that valves are installed on both the pipe connected to the suction pipe 5 and the pipe connected to the bottom of the tank 1. Opening the valves simultaneously activates the first pump 13 and the second pump 14. The first pump 13 drives the cleaning fluid in the tank 1 through the outlet pipe 6 onto the filter cotton 20. The filter cotton 20 filters out the dirt in the cleaning fluid. The filtered cleaning fluid then enters the activated carbon 24 for further filtration. The activated carbon 24 adsorbs fine impurities in the cleaning fluid. The second pump 14 then re-feeds the cleaning fluid treated by the activated carbon 24 from the bottom of the tank 1. Figure 3 As shown by the black arrow, the cleaning fluid flows upward at a certain speed. Since there is a gap between the blocking net 23 and the top of the stationary resin, the cleaning fluid flowing from bottom to top can lift the resin, causing many resin particles to tumble, thereby generating friction between the resin particles and allowing the impurities on the resin surface to fall off quickly.

[0030] The detached dirt can be sucked out through the suction pipe 5, and then the sucked dirt is drawn into the outlet pipe 6 through the first pump body 13. Finally, it falls onto the filter cotton 20 for filtration, and then enters the bottom of the tank 1 after being adsorbed and filtered by the activated carbon 24. This cycle is repeated. When the cleaning liquid coming out of the outlet pipe 6 is clean, the resin cleaning is complete.

[0031] Furthermore, such as Figure 2 As shown, a control cabinet 17 is also provided on the top of the base 12. The control cabinet 17 is equipped with a controller, which is electrically connected to the first pump body 13 and the second pump body 14 respectively, so that the controller controls the rotation of the first pump body 13 and the second pump body 14.

[0032] During the cleaning operation, the suction flow rate of the second pump body 14 is less than the discharge flow rate of the first pump body 13. To prevent the cleaning fluid in the filter box 7 from overflowing, the controller is also electrically connected to two liquid level detectors 18. Figure 2 Hehe Figure 3 As shown, one level sensor 18 is located on top of the filter box 7, and the other is located below the support mesh 19;

[0033] The liquid level detector 18 located at the top of the filter box 7 is used to detect whether the liquid level of the cleaning fluid exceeds the limit value. When the liquid level detector 18 alarms, the first pump body 13 and the second pump body 14 immediately stop working. At this time, it is necessary to check whether there is any blockage in the pipeline. The first pump body 13 and the second pump body 14 must not be started until the cause is eliminated.

[0034] The liquid level detector 18 located below the support net 19 is used to detect whether the cleaning fluid level has reached the set value. Because the suction flow rate of the second pump body 14 is less than the discharge flow rate of the first pump body 13, when the liquid in the filter box 7 reaches the liquid level detector 18, the first pump body 13 stops pumping, while the second pump body 14 continues to run. This allows the first pump body 13 to pump when the cleaning fluid level is lower than the set value, and to stop pumping when the cleaning fluid level reaches the set value, so that the liquid level in the filter box 7 is always kept at the set value. This allows the second pump body 14 to continuously send the cleaning fluid into the bottom of the tank 1.

[0035] Finally, after cleaning, the pipes can be disassembled from the bottom of tank 1 and the top of suction pipe 5 respectively. After closing the valve, tank 1 can be used to continue filtration.

[0036] Based on the above embodiments, further optimization can be achieved by providing brake casters at the four corners of the bottom of the base 12 to facilitate the movement of the entire device.

[0037] Based on the above embodiments, further optimization is possible: the liquid outlet pipe 6 is installed inside the top of the bracket 9, the bracket 9 is installed on the top of the filter box 7 by bolts, and the end of the liquid outlet pipe 6 is bent in an L-shape towards the filter cotton.

[0038] Based on the above embodiments, further optimizations can be made, such as... Figure 4 The location indicated by the middle arrow A is where a filter screen is installed at the connection between the pipe at the inlet of the second pump body 14 and the bottom of the filter box 7, to prevent activated carbon from entering the second pump body 14.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
